Good luck! because there’s nowhere near enough Rare Earth Metals in the ENTIRE world to replace a fraction of the 2 billion or so passenger automobiles now in use.

Yet another reason why we should shift focus to midgets.

Midgets can pull rickshaws. Wouldn't that be fun?

For long distances, you could have way-stations where you
get fresh midgets just like Pony Express. Except with midgets.

Midgets are green energy if you feed 'em carrots and spinach.

They LOVE that stuff.
